Abstract: Loaded rail cars in succession are positioned at an unloading station adjacent to plural connected car lifting and inverting jaw devices which revolve around a common horizontal pivot axis extending lengthwise of the car and across the jaw devices. First power operators connected between the relatively movable jaws of the devices produce the required relative movements of the jaws of the devices in unison to effect gripping of each loaded car in preparation for raising, inverting and emptying its contents into a receiver, and subsequently releasing each car following its return empty to an upright position at the unloading station. Second power operators connected between a stationary base and the jaw devices serve to rotate the jaw devices around the common horizontal pivot axis with each car toward and from the car emptying and upright positions. The rotating jaw devices may be counterweighted to reduce the power required to move them around their common pivot axis.

Abstract: The elevated projection head of a conventional overhead projector is equipped with a flip panel of opaque material which, in a free-hanging vertical position, blocks light from the projection head and, in a raised position, is clear of the projected light path. The flip panel is attached to the projection head by a free-flexing hinge element to facilitate flipping the panel between its two positions of use. During presentations made with use of the overhead projector, the necessity for turning the projector off and on during brief interruptions of the presentations or while changing transparencies is eliminated. The structure of the projection head need not be altered to accept the flip panel attachment.

Abstract: Pipets of virtually any size are delivered automatically and continuously with the assistance of gravity to an intermittent rotary transport mechanism which carries each pipet separately to a plugging station. At the plugging station, each pipet is engaged and held against movement while precut cotton plugs are inserted into the pipets by a reciprocating needle device controlled by a mechanism which simultaneously controls and coordinates the activity of scissor blades which sever a cotton roving during a dwell of a roving transport wheel on the shaft of the pipet rotary transport mechanism. After being plugged, each pipet is delivered from the rotary transport mechanism onto a collection apron. A multi-position stop element on the inclined pipet delivery rails of the machine allows pipets of varying diameters to be plugged with precision without requiring additional machine adjustments.

Abstract: A wheel suspension system for special event trailers is constructed in two opposite side laterally narrow and compact units attached to the lower perimeter frame of the trailer body. The trailer body is elevated to a transport position and lowered to a stable ground level position convenient for customers by the operation of horizontally movable cam lift plates powered by horizontal axis hydraulic cylinders in cooperation with vertical axis carriage plates having cam followers. Longitudinal leaf springs rockably mounted on the carriage plates have lost motion connections with tandem wheel axles carried by crank arms pivotally attached to the lower perimeter frame.

Abstract: An automatically engageable and quickly and easily releasable locking device for a toilet seat and lid is disclosed. A single mounting bar attached to the underside of the lid carries a pivoted spring-biased locking arm which is released by simple finger pressure and returns automatically to a positive locking position in contact with a stop whenever the lid is closed. No reconstruction or alteration of the conventional toilet bowl or seat and lid structure is required. The locking arm may also be gravity returned to its locking position without spring action.

Abstract: A precision level embodying solid state electronics is disclosed. A level body portion contains chambers for paired light emitting diodes operable to indicate angular deviations from true horizontal and true vertical over desired ranges. A mercury droplet in each compartment is in contact with an arcuate conducting strip leading to a battery terminal of one polarity. Upon angular displacement of the level, the mercury droplet sequentially contacts light emitting diode leads of like polarity. The light emitting diode leads of opposite polarity are connected through a common conductor element and an on-off switch of the level to a battery terminal of like polarity. The same switch is operably connected with the groups of light emitting diodes used to indicate angular deviations from the true horizontal and true vertical. The light emitting diodes may be embedded in a clear transparent medium or in variously colored translucent elements.

Abstract: An unpressurized heater for water or another liquid includes a shell which may be substantially filled with liquid to be heated and within which is immersed a fire box which delivers hot combustion products through fire tubes above the fire box which are themselves surrounded by the liquid contained in the shell. The fire box may be fired by gaseous, liquid or solid fuel. A secondary heat exchanger or heat exchangers within the shell also immersed in the liquid can receive salt water or other fluid which is heated proportionally to the temperature of the liquid in the shell and is circulated through a diver's suit and is ultimately returned to the sea after warming the diver. Back-up heating elements are included for diver applications along with required controls and instrumentation in dry compartments. Built-in fuel storage tanks complete a self-contained system.

Abstract: The width of a laterally foldable wheelchair can be reduced by the chair occupant by manipulation of a hand lever on one side of the chair frame which is operable to elevate a flexible seat support member thereby inducing partial folding of the chair to reduce its width. The weight of the occupant on the chair seat tends to bias the hand lever toward its inactive stowed position.

Abstract: Nuts on the ground are propelled by an air jet issuing from one tubular branch of a hand-held nut harvester into an opposing conveyor branch where the nuts are lifted until they strike a deflector in a separator chamber. Deflected nuts descend from the separator chamber to an attached collection receptacle. Debris entrained with nuts in the conveyor branch of the harvester is subjected to a venturi action produced by convex and concave spoon-like elements in the throat of the separator chamber immediately beyond the nut deflector and is swept through a rear downturned debris conduit or horn. The harvester can clear itself of debris through operation of an air stream diverter valve which diverts most of the harvesting air stream produced by a back-pack blower on a reverse path through the conveyor branch of the harvester.

Abstract: A golf club, such as a driver, includes a body portion formed of natural uncompressed hard wood having an angled face on one side thereof. A wedge component formed of laminated highly compressed densified wood is bonded to the angled face of the body portion and forms a striking face and partial bottom face for the club head. Weight is concentrated near the striking face and bottom face to improve club controllability, balance and striking efficiency. Pre-weighing of wood veneers prior to compressing enables control and location of club head center of gravity. Final shaping of the club head is accomplished on a copying lathe.

Abstract: A vending machine for newspapers and magazines has the capability of dispensing one newspaper at a time to a customer following insertion by the customer of proper coins into a conventional coin mechanism. The insertion of the coins releases a normally locked dispensing lever which the customer need only pull a single time in one direction. A roller activated by the dispensing lever buckles the topmost newspaper in a stack on a biased platform to release the folded edge of the newspaper from beneath a biased hold-down plate, the released newspaper gravitating onto a delivery tray near the bottom of the machine where it can be picked up freely by the customer. The delivery system resets itself automatically for the dispensing of additional newspapers, one at a time, sequentially, from the top of the stack each time the dispensing lever is returned automatically to the non-dispensing position where it remains locked until proper coins are again inserted.

Abstract: Air or any other gas in a moving stream possessing kinetic energy is impinged on a foraminous barrier having a multitude of dissimilar adjacent nozzle orifices. Such impingement converts the kinetic energy of the stream to internal energy within the gas; and compression through the nozzle orifices of the foraminous barrier also increases the internal energy and reduces the pressure of the air or other gas (Bernoulli's principle), and greatly increases the downstream intensity of turbulence in the flowing air or gas. This treatment conditions the air, after its expansion in a processing chamber, to effect mixing with and rapid vaporization of liquid substances at low temperatures without the addition of external sensible heat, or with less external sensible heat, thus effecting savings of energy in many industrial, commercial and consumer applications.
